GHG emissions (carbon dioxide, methane and nitrous oxide) from food consumption were calculated using the database developed herein and the population projections developed for the following SSPs, as outlined by Riahi et al. 57 : Regional Rivalry, Inequality, Middle of the Road, Fossil-Fuelled Development and Sustainability (corresponding to SSP3, SSP4, SSP2, SSP5 and SSP1, respectively). The future warming associated with consumption from a constant 2020 global population is also provided for reference. RCP8.5 emissions were input for all sectors other than agriculture and all forcers other than carbon dioxide, methane and nitrous oxide to develop all-forcing baseline simulations from which the isolated food consumption temperature responses were derived (see Extended Data Fig. 1 for the results using RCP4.5 emissions). The shading represents 95% confidence intervals based on 190 ensemble members and the lines represent the mean of these ensemble members. The Inequality (SSP4) scenario is identified by a dotted line to better visualize overlapping results.
